Title: Driving method for active matrix panel
Inventor: SATO TAKASHI
IPC: G02F1/133
Filed: 1988-12-27
Abstract: PURPOSE:To form an active matrix panel with high display quality by specifying a voltage applied to a material which has electrooptic effect. CONSTITUTION:The effective value of the voltage applied to a material with electrooptic effect and a nonlinear material from each scanning line and each data line in one frame period is set between V10 (the effective value of the voltage with which the light transmissivity of the material with the electrooptic effect is 10%) of the material with the electrooptic effect and V90 (the effective value of the voltage with which the light transmissivity is 90%). Namely, when the voltage applied to the material with the electrooptic effect is between V10 and V90, the light transmissivity of a defect picture element is 10 - 90%, so the defect picture element is neither too bright nor too dark and its presence comes to extremely hard to recognize. Consequently, the high display quality of the active matrix panel is realized.

Abstract: PURPOSE:To reduce center segregation in a cast slab by transferring ultrasonic vibration to surface of the cast slab so that amplitude of the ultrasonic vibration in the cast slab comes to leveling at high level after becoming more than the specific value of the solid phase ratio at axial center part of the remained molten steel in the cast slab or just after completing the solidification. CONSTITUTION:In order to make long distance of shifting stroke under pushing ultrasonic vibration transmitting horns 4, 5 to the cast slab 1 and raise the efficiency, the method for pushing the horn to the side faces of the cast slab 1 is applied. Two ultrasonic vibration generating systems are operated with the same frequency and power, and two horns 4, 5 are arranged as shifting by 1/4 of wavelength to the casting direction of the cast slab 1 and while holding this interval, the cast slab and the horns are synchronously shifted. After shifting to the casting direction for the prescribed time, the horn is apart from the cast slab and again pushed to the cast slab from upstream side. Plural horns are arranged so that the relative distance between the horns comes to shift to the phase of the ultrasonic at the position of >0.8 the solid phase ratio fs at the axial center part of the remained molten steel. By this method, the amplitude of the ultrasonic vibration is made to leveling at high level and center segregation viewed in semi-macro segregation can be remarkably improved.
